0.1667

Explanation:

Hello,

Dalton's law defines:

A total pressure is:

So, for A (solving for in the previous equation, we get:

Since , we obtain:

}

Best regards.

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
